Global temperatures experienced a pronounced slowdown or negative anomaly between 1950 and 1980, which multiple lines of research attribute to aerosol masking and global dimming offsetting greenhouse gas warming.
The retrieved papers consistently support the claim that anthropogenic aerosol forcing and related reductions in surface solar radiation (global dimming) contributed to a negative temperature anomaly or a leveling off of global and regional temperatures from the 1940s/1950s through the 1970s.
